UFC 134, first announced as “UFC: Rio,” takes place Aug. 27 at HSBC Arena in Rio De Janeiro, and the night’s main card airs on pay-per-view.

Assuncao vs. Eduardo is slated for the preliminary card.

Assuncao long has been rumored for the card, largely because the fighter campaigned heavily for a fight in his home country. However, the Brazilian jiu-jitsu black belt likely finds himself in a must-win situation. After a 3-2 run in the WEC, he made his UFC debut and suffered a first-round knockout loss to Erik Koch at UFC 128. His current 1-3 skid followed a 15-1 start to his pro career.

Eduardo, a fellow Brazilian, joins the UFC in the midst of an 11-fight win streak that dates back to 2008. A veteran of the Brazilian fight circuit, Eduardo also made an appearance under the Bellator banner, when he scored a decision victory over Donald Sanchez at Bellator 3 in 2009. Of his 25 wins, 19 have come via stoppage (13 via submission).
